In packaging and brand building, frosted glass bottle marking not only affects the product’s aesthetics but also determines the clarity and durability of the information. Choosing the right marking technology ensures a long-lasting, precise mark without damaging the bottle.
1. UV Laser Marking: The Premium Choice
UV laser uses a 355nm wavelength and applies cold processing technology with minimal thermal impact. It delivers high-definition, fine engraving on frosted glass surfaces, making it ideal for logos, QR codes, and batch numbers. It keeps the bottle intact while providing high-contrast marks, making it the top solution for frosted glass bottle marking.
2. CO₂ Laser Marking: Efficient and Cost-Effective
CO₂ lasers operate at a 10.6μm wavelength and can quickly mark text and simple patterns, suitable for high-speed production lines. However, due to higher thermal impact and lower precision compared to UV lasers, careful power adjustment is needed to prevent cracks.
3. Inkjet Printing: Temporary Marking Solution
Using special inks, inkjet printing can add variable information such as production dates and batch numbers. However, it offers poor adhesion, is not scratch-resistant or waterproof, and is best suited for short-term product labeling.
4. Screen Printing: Color Decoration Option
Screen printing allows for colorful logos and decorative designs, but the process is complex and less flexible, making it suitable for large-scale, fixed-pattern applications.
Conclusion: If you aim for precision and permanence, UV laser is the best choice for frosted glass bottle marking. If you prioritize speed and cost efficiency, CO₂ laser is a practical alternative.
